Increases the heart rate

What happens to blood pressure when a patient assumes a sitting or standing position?

Blood pressure decreases

What is the correct method for calculating heart rate using the radial artery pulse?

Count the pulse beats for 30 seconds and multiply by two

When should you take an apical pulse instead of counting the radial artery pulse?

If the radial pulse is abnormal in any way

What is the purpose of recording the heart rate on paper or a flow sheet?

To document and track changes in heart rate over time

Which artery is typically used to assess the heart rate?

Radial artery

Why should you count the pulse for a full minute if it is abnormal in any way?

To ensure accuracy of the measurement

Heart rate

Study Notes

Pulse Rate in Infants and Children

  • Newborn to 1 month: 130 BPM
  • 1-12 months: 80-120 BPM
  • 1-2 years: 80-120 BPM
  • 2-8 years: 80-100 BPM
  • 8-12 years: 70-90 BPM
  • 12 years and above: 60-80 BPM

Factors Affecting Pulse Rate

Sex

  • After puberty, average male pulse rate is slightly lower than female

Exercise

  • Pulse rate increases with exercise

Fever

  • Pulse rate increases in response to lowered blood pressure due to peripheral vasodilation and increased metabolic rate

Medications

  • Digitalis preparation: decreases pulse rate
  • Epinephrine: increases pulse rate

Environmental Factors

Heat

  • Pulse rate increases as a compensatory mechanism

Stress

  • Increases sympathetic nerve stimulation, increasing heart rate and force of heart beat

Position Changes

  • When assuming a sitting or standing position, blood pools in dependent vessels of the venous system, affecting pulse rate

Measuring Pulse Rate

  • Count pulse beats for 30 seconds and multiply by two to get rate per minute
  • Count pulse for full minute if it's abnormal in any way
  • Take an apical pulse to measure heart beats per minute

Test your knowledge on the factors influencing heart rate, from the normal range for newborns to the effects of exercise, fever, medications, heat, and stress on pulse rate. Explore how gender, exercise, fever, medications, heat, and stress can impact heart rate.
